Summary

[edit]
Description
Français : Essai de traction sur une éprouvette plate en acier SAE 1045 (équivalent du C45 selon la désignation EN) à température ambiante. Comparaison entre la courbe conventionnelle R = ƒ(e ) et la courbe rationnelle σ = ƒ(ε). Mise en évidence de la droite élastique et de la striction.
English: Tensile test of a flat specimen made of SAE 1045 steel (equivalent to grade C45 in EN system) at room temperature. Comparison between the engineering curve R = ƒ(e ) and the true curve σ = ƒ(ε). Elastic line and necking highlighted.
